If variable var does not exist, creates var and
initializes it to
expression , list , or matrix .
If
var already exists and if it is not locked or
protected, replaces its contents with
expression ,
list , or matrix .
Hint: If you plan to do symbolic computations
using undefined variables, avoid storing anything
into commonly used, one-letter variables such as
a, b, c, x, y, z, etc.

0b binaryNumber
0h hexadecimalNumber
Denotes a binary or hexadecimal number,
respectively. To enter a binary or hex number,
you must enter the 0b or 0h prefix regardless
of the
Base mode. Without a prefix, a number
is treated as decimal (base 10).
Results are displayed according to the
Base
mode.
In Dec base mode:
0b10+0hF+10 ¸ 27
In Bin base mode:
0b10+0hF+10 ¸ 0b11011
In Hex base mode:
0b10+0hF+10 ¸ 0h1B
